BUILDING CONSTRUCTION.

' Application filed February 4. 1927. Serial No. 165,917.-

My invention relates to improvements n building construction, more particularly in the making of concrete flooring, and 1t consists in the combination, constructions, and arrangements herein described and claimed.

An object of my "invention is to provlde a floor which is light, shallow, and yet whlch has great relative strength.

A further object is to provide a construction in which the ceiling is level, with no projecting beams.

A further object .is to provide a buildlng construction in which there is a saving in the cost of materials, an economy in the use of forms, and with considerably reduced dead loads.

A further object is to provide a building construction which will give-greater stiffness against forces such as wind.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a plan view showing a floor in the course of construction,

Figure 2 is an enlarged section along the line 22 of Figure 1, with the addition of the cement filling covering the ans,

Figure 3 is asection at rig t angles to Figure 2 along the line 3-3 of Figure 2, and

Figure 4 is a perspective view of pans and metal sofiit used in the building construction.

In the following description, I will make use of definite dimensions in specifying the arrangement of the various parts, but it will be understoodthat this is for sake of illustration only and that other dimensions than those given might be used without departing from the spirit and the scope of the mvention.

In carrying out my invention, I make use of a metal framework consisting of steel girders ,5 which are preferably I or H beams. These girders may be spaced say eighteen feet apart in both directions. In Figure 1 I have shown a square made up of such girders.

Between the girders, I place wood-form soflits 6. These are preferably 2 x 6 planks laid about 3' and 9" (centers) apart and they are shored up as by supports 7 of any suitable nature. A form 8 may be used underneath the girder 5 with a suitable support 7.

It will be noted that the wood soflits are laid in one direction only. Upon these sofiits I place pans 9, such as that shown in Figure 4. These pans have preferably square tops and their sides are placed substantially three inches from the pans in the adjacent row and also the same distance from the adjacent pa-ns'in the same row. Between the pans of the same row, I make use of'a metal sofiit such as that shown at 10 in Figure 3. This is of U-shaped form and, as will be observed, is inverted with respect to the adjacent pans. The edges of the U-shaped soffit rest on the wood soflit 6 and the soflits 10 form closures for the ends of adjacent pans 9.

In Figure '1 I have shown two rows of these pans. When they have been placed in position, reinforcing rods such as those shown at 11 are placed in the spaces between the rows of pans as well as in the metal sofiits and then the cementlQis poured and is left to harden. Now, when the supporting forms are removed, there will be a floor section between the girders consisting of recesses where the pans were placed and concrete beams in the spaces between the pans as well as those formed by the metal soffits. These beams will form integral supporting members running at right anglesto each other.

It will be seen that in the use of this construction I have made a floor which is strong and yet light and comparatively shallow.

Furthermore, the use of the metal sofiits obviates the necessity of wood-form soifits and the supporting of these soflits between those which are arranged longitudinally.

When the concrete forms have been removed, it will be observed that the under side of'the concrete beams thus made are in the same horizontal plane, so that when the ceiling is finished, as by placing metal lath underneath the beams, and the latter is plastered, the ceiling will be fiat and will not have beams projecting down below it as in other forms of concrete construction.

I claim:

1. The herein described process of making concrete flooring, which consistsin providing a series of parallel rows of sofiits, placing on said soliits rows of pans spaced equally apart from others in the row and from similar pans in adjacent, rows, in clos-- ing' the ends of the pans in any row by U- shaped soflits, in placing a layer of concrete over the pans and in the spaces therebetween, and subsequently removing the pans and sofiits, whereby a floor having beams running at right angles to each other is formed.

2. A building construction comprising a series of soffits disposed in parallel relation,

said soflits being spaced apart, pans having 1 tween the spaced-apart pans for closing the 15 open ends of said pans.
